N2 - As an effort, not a mutually exclusive but rather complementary to developing better backplane bus, this paper considers adapting distributed shared-memory (DSM) architectures to improve traditional shared-bus designs. We consider two well-known DSM architectures, namely Cache-coherent Non-Uniform Memory Architecture (NUMA) and Cache-Only Memory Architecture (COMA), in reducing bus traffic. Our study shows that COMA provides excellent opportunity of significantly reducing bandwidth requirement for the bus while cache-coherent NUMA provides a marginal improvement.
